BRUSH.

SPJECEEATIGN forming part of Letters Patent No. 335,876, dated February 9, 1886.

Application tiled May 1,1894. Serial No.4 130,044. (No model.)

To all whom t may concern:

Be it known that l, Jarras F. BAnrLnrr, a citizen ofthe United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Brushes; and I do .hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use them.

The invention relates to brushes.

The object ofthe invention is to produce a paint, whitewash, or other brush in which the bristles are readily inserted and securely held, that shall be of ready, compact, and durable construction, and in which a wedge, tapering plug, or bell, ofthe kind exhibitedin `my patent dated January 2, 1883, and numbered 269,910, may be employed, in connection with a retainingband, with comparatively slight insertion of the bristles into the band and without the broad end of the wedge or plug projecting much or at all below the band. To this end l supply primarily a piece of wood or other material provided with an opening countersunk from within, this piece so pro; vided to form a bottom piece or seat, provide this piece then with a band, and use both in connection with awedge, tapering plug, or bell, the band encircling the bottom piece or seat, and the opening in the bottom piece countersunk therein, being of a shape suitable to receive the body of the wedge, plug, or bell, whereby when bristles are placed in the band with their ends against the bottom piece the plug forced into the countersunk opening will hold them securely in place against the band, while, for convenience in use, to the bottom piece or to the plug may be attached a suitable handle.

In the accompanying drawings, forming part of this specification, like letters of reference indicate corresponding parts.

Figure l is a longitudinal section of a brush embodying the invention. Fig. 2 is a perspective view of the band. Fig. 3 is a perspective view of the bottom piece or seat. Fig. 4 is a perspective view of a band or cap with the bottom piece in position. Fig. 5 is a perspective view of the leaderan instrument which may be employed in inserting the plug. Fig. t3 is a view of one form of the wedge or plug,

and with a shank attached thereto,and shown as provided with a screw.

A represents the band, which in the present illustration is of metal, and which may be of any suitable shape and of any size proper to,

hold the required quantity of bristles.

3 is a piece of wood or other suitable 1naterial to form a bottom piece or seat, and is proA vided with a central opening, C, countersunk in one piece.

` D is a wedge or tapering plug,of less diameter at its greatest width than the band, and in the present insta-nce is shown in the form of a conical bell, but would be modified in contiguration according to the shape of the band employed. The piece Bis inserted into the band in such manner as to leave the side with the countersunk portion of the central opening inward, and may form a top upon the band. lt should be of suificient thickness to be pushed into the band to such distance as nearlyto fill it and leave but a small portion of the rim of the band projecting below it, or only about enough to insure aiirm hold upon the bristles. In practice, for an ordinary paint-brush,l have found about three-eighths of an inch of rim projecting below the bottom piece to sufiice. The eountersunk opening in the bottom piece is of a shape conforming to the configuration of the wedge or plug. Theplug employed in this case is not a mere short wedge or cone, or a concavo-convex disk, but is a somewhat elongated wedging-piece, and therefore in order to be able to drive it up within the short projecting rim it is essential that the bottom piece should be cut away to receive it. By providing a recess for the plug to enter I am enabled while using a very short rim for insertion, thus saving -on the bristles by shortening the requisite insertion, to use the somewhat elongated plug described in my patent of January 2, 1883, No. 269,910, and get a more gradual and longer wedging or binding action from vthe plug against the band. than if a plug no longer than the projecting rim were employed.

It is obvious that the plug may be forced into position in various ways, the main feature of the invention being the combination of an expanded or wedge-like binding-plug with a retaining-band and a block having a recess to receive the plu.

IOC)

The band, bottom piece, plug tightly driven into place, and the bristles will alone constitute a brush suitable for many purposes; but when an elongated handle is desired I'prefer to provide the plug D with a shank, E, which may be provided with retaining means, such as a wood-screw. G is an instance of such a handle, and in the present case I have shown the screw as passing up into the handle.

To facilitate the introduction of the plug, the leader H will be found convenient. This leader consists of a needle-shaped instrument having one end plain and pointed and the other provided with means-such as a depression, g-for receiving and holding the end of the shank E.

In the present instance the manner of putting the parts of the brush together will at once be apparent. The requisite quantity of bristles is tirst placed in the band, after which the lbottom piece is inserted. Next the leader is passed through the bristles until the point shows through the hole in the bottom piece. Then the shank is insertedinto the leader, and then the plu gis passed among the bristles with its narrow end foremost and forced up to the opening in the bottom piece the necessary distance to hold them firmly in place by driving it into position, where it`will remain without fastening, ready for the handle. After the shank or' the plug emerges from the hole the leader is removed. As the bristles become loose in use of the brush or otherwise, the plug may be forced farther' within the band, when its gradual increase in width will insure a tighter fastening of the bristles against the rim.

I make no claim in this case to the combina tion, with apiece of wood or other substance, forming a top piece or bottom piece, of a surrounding band, the lower end of which extends below the lower face of the piece, and a center piece adapted to be drawn within the cup by the screw to hold the bristles securely therein, since such is included in another application tiled by me; but7 Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The bottom piece, B, Jrovided with a tapering opening in one face thereof7 substantiall y as described.

2. A bottom piece having a tapering opening countersunk in one face and provided with an encircling band, leaving a short projecting rim, as and for the purpose set forth.

3. The combination, with a wedge, tapering plug, orbell, of a band encircling and permanently holding a bottom piece or seat, provided with an opening countersunk from within, and of a shape suitable to receive the body of the wedge, plug, or bell, substantially as and for the purpose set forth.

4. A brush made up ofa band A, encircling and holding a bottom piece, B, inserted in such manner as to leave a projecting rim on said band, and provided with a tapering eX- cavation from within, a wedge or plug capable or" entering bodily into the excavation, and suitable bristles having their upper ends against the bottom piece and interposed between the plug and the band.

5. In combinationwith a band encircling a bottom piece or seat provided with an opening countersunk from within and of suitable shape, a wedge, plug, or bell adapted to enter the opening, and provided with a shank, and a handle fitting upon the shank, arranged and operating as described.
